DNS Lookup
Query A, AAAA, MX, TXT, NS, SOA, CNAME, and CAA records for any domain.
About the DNS Lookup
DNS lookup queries the public DNS records for a domain and shows them grouped by type. Enter a domain and pick a record type, or leave it on All common to fetch A, AAAA, MX, TXT, NS, SOA, CNAME, and CAA records in one go. It is the quick way to see how a domain is configured without reaching for the command line.
Each record type answers a different question. A and AAAA point a name at IPv4 and IPv6 addresses. MX lists mail servers. TXT holds verification, SPF, and other text values. NS names the authoritative nameservers, and SOA shows the zone’s serial and timing. CNAME is an alias to another name, and CAA controls which certificate authorities may issue certificates for the domain.
Use it to verify a migration propagated, to read a domain’s SPF or verification TXT records, to confirm nameservers after a transfer, or to check CAA before requesting a certificate. Results reflect what the resolver sees at lookup time; recently changed records may still be cached elsewhere until their TTL expires.
The query runs on our server, which asks public DNS on your behalf, because browsers cannot make raw DNS queries. The domain you enter is sent to our server only to perform the lookup and is not stored or logged.

Frequently asked questions
Which record types can I look up?
A, AAAA, MX, TXT, NS, SOA, CNAME, and CAA. Choose one from the menu, or use All common to retrieve every one of them at once.
Does this run in my browser?
No. Raw DNS queries are not possible from a browser, so the lookup runs on our server and returns the records. The domain you enter is sent to our server for the lookup and is not stored.
I changed a record but it still shows the old value. Why?
DNS is cached according to each record’s TTL. The resolver may still hold the previous value until that time passes. Lower the TTL before a planned change so updates propagate faster.
What is a CAA record for?
CAA lists which certificate authorities are allowed to issue TLS certificates for your domain. It is a guard against mis-issuance; if it is too strict it can also block a CA you actually want to use.
Why do I see no TXT or CNAME records?
Not every domain publishes every type. An empty result for a type simply means none exist at that name, which is normal, for example a root domain rarely has a CNAME.
